Application Scenarios & Design Considerations

8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY, ADC, 16-BIT TIMERS, SPI,

Alternative Part Number

  • MC68HC908QY4CDW --: 8-bit HC08 microcontroller with similar GPIO, timer and memory resources, widely available and pin-compatible in many designs.
  • PIC16F648A-I/SO --: Popular 8-bit flash microcontroller with comparable I/O count and peripherals, easy migration path with strong toolchain support.
  • AT89C4051-24SU --: Low-cost 8051-compatible 8-bit MCU with similar small-package footprint and basic peripherals, suitable for simple control applications.
  • ST72F324K6T6 --: Same ST7 8-bit core family with Flash memory, similar peripheral set and package options; a common drop-in upgrade path when the OTP-based ST72C104 is unavailable.
  • STM8S104K6T6 --: STMicroelectronics' newer 8-bit STM8 core is the recommended successor to the ST7 line, offering comparable I/O, timers and memory with better availability and tool support.
  • PIC16F877A-I/P --: Widely available 8-bit MCU with comparable memory, timers and I/O count; a practical cross-vendor fallback if ST7 parts cannot be sourced, though pinout and code changes are required.
